Experiments were conducted to investigate the fate of ethylbenzoate and soil microorganisms in shallow aquifers. Biodegradation and volatilization have been identified to be the major mechanisms in attenuating ethylbenzoate in contaminated soils. The parameters of an available model have been obtained by fitting it to the experimental data. Various facets of biodegradation, including the effect...

Several bacterial strains carrying genes determining mercury resistance on naturally occurring plasmids will convert 10(-5)m Hg(2+) (chloride) to a form of mercury which is volatile and soluble in organic solvents. The volatilization activity is induced by exposure to HgCl(2).

Abstract At present, automatic control technology is widely used in the field of drying. Although existing processing can basically ensure quality drying, there are some problems, such as low production efficiency, thermal uneven hot air cloth, inaccurate temperature and so on. The application electromagnetic improve efficiency drying processing. It has remarkable energy-saving effect. In proce...

Definition of Drift When liquids are forced under pressure through small orifices (like sprayer nozzles) they are sheared into small aerosols or particles having nearly a thousand fold range in spherical diameters. Owing to gravitational forces and the viscosity of air, the rate of fall to ground can be predicted by Stokes Law and is proportional to the radius of the particles. The rate of fall...

Worldwide gas emissions are being strictly regulated, therefore processes to reduce steam injection for enhanced oil recovery (EOR) require a deeper analysis identify the means contribute environmental impact reduction. Lately usage of additives such as solvent has taken new interest due its positive on improving and energy efficiency reducing greenhouse emissions. In that sense, use nanopartic...

To study the effect of magma intrusion on thermal evolution low-rank coal with high moisture content, relationship between content variation and conductivity was analyzed by COMSOL Multiphysics numerical simulation field validation. Taking Daxing Mine in Tiefa coalfield as research background, effects finite time mechanism volatilization organic maturity seam are investigated this paper. The re...

In 1971, an experiment was conducted in a field containing high amounts of residual DDT (dichlorodiphenyltrichloroethane) to evaluate deep plowing, followed by flooding, with and without organic matter applications, as soil and water management tools to reduce total DDT residues and preferentially degrade the residual DDT to DDD [l,l-dichloro-2,2-bis (p-chlorophenyl) ethane]. The experimental s...
